I've tried both the mode setting and xserver-xorg-video-intel drivers, both result in the same 2-second black screen blips. The happens frequently using chrome, and always when using the gnome screenshot utility. Also, during boot teh screen flickers between black screen and boot splash a lot. setting nomodeset as a grub parameter stops the flickering, but is not a feasible solution as brightness can no longer be set. kind regards, ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: xorg 1:7.7+19ubuntu14 ProcVersionSignature: Ubuntu 5.4.0-25.29-generic 5.4.30 Uname: Linux 5.4.0-25-generic x86_64 ApportVersion: 2.20.11-0ubuntu27 Architecture: amd64 BootLog: Error: [Errno 13] Permission denied: '/var/log/boot.log' CasperMD5CheckResult: skip CompositorRunning: None CurrentDesktop: ubuntu:GNOME Date: Tue Apr 21 08:15:51 2020 DistUpgraded: Fresh install DistroCodename: focal DistroVariant: ubuntu DkmsStatus: rtl8821ce, 5.5.2.1, 5.4.0-21-generic, x86_64: installed rtl8821ce, 5.5.2.1, 5.4.0-24-generic, x86_64: installed rtl8821ce, 5.5.2.1, 5.4.0-25-generic, x86_64: installed ExtraDebuggingInterest: Yes, if not too technical GraphicsCard: Intel Corporation Device [8086:8a56] (rev 07) (prog-if 00 [VGA controller]) Subsystem: Hewlett-Packard Company Device [103c:86c8] InstallationDate: Installed on 2020-04-16 (4 days ago) InstallationMedia: Ubuntu 20.04 LTS "Focal Fossa" - Beta amd64 (20200402) Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 002: ID 0408:5365 Quanta Computer, Inc.
